MACHINE FOR SHARPENING PLOWSHARES.

SPECIFICATION forming part of Letters Patent No. 513,811, dated January30, 1894.

Application filed September 25, 1893- Serial No. 486A4=2. (No model.)

To all whom it may concern.-

Be it known that I, SIMON S. MORRILL, a citizen of the United States,residing at Stockton, in the county of San Joaquin and State ofCalifornia, have invented certain new and useful Improvements inMachines for Sharpening Plowshares; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

. My invention relates to certain improvements in rolling machines andits object is to taper or sharpen metal at the edge and ends 1n convex,concave or any other form, but more particularly for sharpening plowshares, and it consists in a horizontal table, upri'ght standards orbolts and a cap, two rollers, and arms, and a series of cog wheels,pinions, shafts and balance wheels and such other devices andcombination of devices as will be pointed out in the claims and morefully explained in the specification, reference being had to theaccompanying drawings, in whichs Figure 1 is a left hand side elevationof my improved roller sharpener. end elevation of the same. view of therollers. Fig.4 is a detached view of the small pinion. Fig. 5 is adetached top view of the raising incline.

Similar letters of reference indicate corresponding parts throughout theentire views.

A, represents a shell like stand and support for the bearings of thedifferent shafts, such shell having openings on the side for the purposeof admitting a shaft B, such shaft being mounted on boxes 0, which aresecured to and supported by bracket-braces D.

The shaft B is provided at its ends with balance wheels B for thepurpose of securing a steady and continuous motion. Such shaft B is alsoprovided with a pinion E which is rigidly secured to the center of suchshaft. This pinion is-shown in Fig. 4 of the drawings.

F, is a shaft which is mounted on boxes G, situated at the rear end ofthe shell A. H, is a gear wheel mounted on and rigidly attached to thecenter of said shaft F, such gear-wheel H engaging with the pinion E.

Fig. 2 is a rear Fig. 3 is a front The shaft F, at its ends, is providedwith cranks or eccentrics I, which engage with and actuate arms J whichextend forwardly and engage with rollers K and L.

The shell A is provided, at its front side, with a table M which isrendered rigid and exceedingly stout by means of ribs or brackets M,shown by dotted lines Fig. 1.

N, are bolts or standards which are provided, at their lower ends withnuts 0, and at their upper ends with nuts P, and P, such bolts isinserted on the bolts N and between the nuts P and P such cap Q beingprovided with ribs R, which give the cap greater rigidity.

The roller K is adapted to engage with the lower side of the capQ,such-roller having its journals L in the forward ends of the arms J,such arms being widened at their forward ends for the purpose ofreceiving the journal Kof the rollerL which is immediately beneath andis of a less diameter than the roller K.

S, are inclined plates for the purpose of maintaining the roller K inclose proximity to the cap Q, such plates being attached by set screws Sto the table M.

T, are brackets which render the boxes G more rigid. V

U represents a plow share which is placed in a position ready to besharpened.

Power is communicated to the shaft B, thus settingin motion the wheelsB. The pinion E then engages with the gear-wheel H, thus setting theshaft F, the eccentrics I, the arms J, and rollers K and L in motion.WVhen the arms J and rollers K and L are thrown forward by means of theeccentrics I, the plow share,or other article to be sharpened, is thrustbetween the roller L and table M, the rollers being raised by means ofthe inclined plates S for that purpose, whereupon the rollers will bedrawn back by means of the arms .I and eccentrics I which movement drawsthe metal to the required edge or point. The roller L may be of anyrequired design.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a roller sharpener, the combination with'a suitablestand or shellA, and table M; of the two arms J ,provided with rollers K, and L, atone end, the shaft F, the eccentrics I, on

being adapted to engage with a cap Q which its opposite ends, thestandards N, the cap Q on said standards, the inclined plates S, andtheir set screws, the drive shaft, and suitable mechanism for operatingthe same, substantially as shown and described.

2. In a roller sharpener, the combination with the shellA of the shaft Band its balance wheels 13', the pinion E, the gear wheel II, mounted onthe shaft F, the eccentrics I attached to the ends of the shaft F, thearms J attached to such eccentrics, and having their forward endsadapted to receive the journals of the rollers K and L, the roller K,the roller L situated immediately beneath and in close proximity to theroller 'K, the table M, the standards N, provided with adjusting nuts,0, P, P, the cap Q adapted to engage with the standards N,such cap beingat an angle to the table M and adapted to engage the rollers K and Lbetween the cap Q and table M, and the incline plates S attached to thetable M, allarranged and operating substantially as shown and described.

In a roller sharpener, the combination substantially as shown anddescribed, with a suitable stand or shell having strengthening bracketbraces, of a series of shafts, balance wheels, cogwheels and pinions,two arms actuated by eccentrics two rollers of different diametersjournaled in the ends of such arms, the smaller being beneath thelarger, a table provided with standards, such standards adapted toengage with a cap, such cap being adjustable by means of the nuts P andP and also being at an angle to the table M and lifting inclines.

In testimony whereof I afiix my signature in presence of two witnesses.

SIMON S. MORRILL.
